It turns out that we can convert from our pair of 300 minute individual plans to a single 550 minute plan with shared minutes and free mobile-to-mobile calling for the same price we're paying and get free phones. And because I'm an Oracle employee, I get a 20% discount off that "same price", which means things will actually get cheaper.
So we've got new phones now. We'll see how this works. The phones are identical, save that mine is blue and Gretchen's is pink.
Well, we had to be able to tell them apart somehow.
